从DeviceNotifyEventArgs获取usb信

Question

我找不到如何提取插入的usb字母。

我有一个事件，听取插入的USB，但我需要插入的字母，因为我有多个usb端口。

void OnDeviceNotifyEvent(object sender, DeviceNotifyEventArgs e)
{
  MessageBox.Show(e.ToString());
}

打印：

[DeviceType：DeviceInterface] [EventType：DeviceArrival] FullName：USB＃VID_2CE3＆PID_6487＃0000000000000000＃{a5dcbf10-6530-11d2-901f-00c04fb951ed} Vid：0x2CE3 Pid：0x6487 SerialNumber：0000000000000000 ClassGuid：a5dcbf10-6530-11d2-901f-00c04fb951ed

我正在使用LibUsbDotNet.DeviceNotify dll

例如：插入E:\

由于DeviceNotifyEventArgs包含序列号，您可以使用它在WMI的帮助下查找设备号。

这是this answer的改编版本：

// enumerate usb drives
foreach (var drive in new ManagementObjectSearcher("select * from Win32_DiskDrive where InterfaceType='USB'").Get())
    // find driver with known serial number
    if ((string)drive.Properties["SerialNumber"].Value == serialNumber)
        // associate partitions with drive
        foreach (var partition in new ManagementObjectSearcher("ASSOCIATORS OF {Win32_DiskDrive.DeviceID='" + drive["DeviceID"] + "'} WHERE AssocClass = Win32_DiskDriveToDiskPartition").Get())
            // associate logical disk with partition
            foreach (var disk in new ManagementObjectSearcher("ASSOCIATORS OF {Win32_DiskPartition.DeviceID='" + partition["DeviceID"] + "'} WHERE AssocClass = Win32_LogicalDiskToPartition").Get())
                Console.WriteLine("Disk=" + disk["Name"]);

确保将所有内容包装到using中：Get()返回的所有搜索者和收集品都需要处理。
